*Results May Vary!

The factory intake tracts on the third gen Infiniti G35 V35 and first gen FX35 S50 were not designed for maximum performance. The Nissan 350Z, which shares its engines with both the V35 Infiniti G35 and FX35 vehicles, and are equipped with a much more efficient intake tube that breathes easier and cooler than its Infiniti counterparts.

The STILLEN Z-Tube is so efficient that it is a direct replacement of the OEM design from a Nissan 350Z, putting out enormous power gains of 11 horsepower!

Made of a roto-mold plastic, the Z-TUBE intake duct offers excellent insulation properties, repelling heat coming off the surface of the engine. As a result the cold intake power increased dramatically. The maximum gains are only achieved when matching up with a STILLEN Hi-Flow Intake filter, part# 402835 , that also includes a polyurethane heat shield for a true cold air intake.

The Venturi ring acts as a velocity stack, speeding up and directing the airflow into the intake chambers, producing a noticeable power bump. The Intake System also lends a more aggressive tone to theV35 G35 and S50 FX35 when pressed, but remains unobtrusive at cruising speed.
